Prophet: Problems Installing in R package ‘prophet’ is not available (for R version 3.3.2)

[Earththing]

I am attempting to follow the documentation for installing in R
when I get to installing the package I get:

install.packages('prophet')
Warning in install.packages :
package ‘prophet’ is not available (for R version 3.3.2)

I have tried a couple different CRAN mirrors.
Running R 3.3.2 on Windows 7 64bit. I looked at the CRAN page and if I am reading it correctly it should work, I see other people with questions using this version of R and have gotten to the point of having usage questions. It has been a while since I used R. What am I missing?

Having exactly the same issue with the same configuration (MRO 3.3.2 + Win7 x64).

Hm I wonder why it isn't finding it. Could you paste the output of these commands?

ap <- available.packages()
nrow(ap)
"prophet" %in% rownames(ap)

Also, is this in a fresh R session? One possibility if this is a resumed session might be that it is using a stale cache of CRAN from before Prophet was uploaded.

That gave me the clue I needed. Apparently the version of R I just started using had an old CRAN snapshot that it uses by default.
Here is the results of the commands and what I did to get Phrophet installed for me:

ap <- available.packages()
nrow(ap)
[1] 9393
"prophet" %in% rownames(ap)
[1] FALSE

Restarting R session...
